That site is using a theme from a provider that is not mentions/supported/chased out of the building (virtually) for being very non-GPL compatible.

Non GPL products are not welcome in the WordPress community. Official WordPress policy states that all plugins and themes that are publicly released are required to adhere to http://wordpress.org/about/gpl/

Any support requests for non-GPL products are usually ignored, in the interests of supporting the community and its freedoms.
